Description
The DM-S-8015 is a compact hollow-shaft BLDC servo motor with an integrated motor driver and 14-bit single-turn absolute encoder, designed for precision rotary motion, robotics, automated turntables, inspection equipment, and industrial automation systems.
Operating at a nominal 24V with a supported voltage range of 12–40V, the motor provides 1.2 N·m nominal torque and up to 3.7 N·m peak torque. Rated speed is 354 RPM, with a no-load maximum speed of 516 RPM.
The integrated control system supports both RS485 and CAN communication, reducing the need for an external servo drive and simplifying system integration. The large hollow-center structure also provides additional flexibility for mechanical integration and cable routing.
With its integrated 14-bit absolute encoder, compact Ø79 mm body, and dual communication interfaces, the DM-S-8015 is well suited for applications requiring precise position, speed, and torque control.
